r20538: Web Application Framework
- correct an error message in the JSON-RPC server
- provide a common RPC request function
- make it easier to have multiple pending RPC requests. this allows an
application-specified request to return "not logged in"; authentication
information to be requested and sent; and the original request to be
reissued.
- in statistics module, if a time is provided as zero, leave it blank rather
than displaying 1 Jan 1970. this showed up in the last_used_at field in the
SMB status report.
- clean up makefile: remove no-longer-used hard-coded path and install target;
remove "chmod" and "nice" commands which were part of the original skeleton,
since that is not deemed appropriate for samba makefiles
